So how do you translate this to English than?cite: "I want to know if it is possible (and if so, how) to trigger the click event that displays the enquiry form on the contact page if the page is accessed via the above link?"
Anyways, thanks for sharing with the community.
In javascript at least, you don't need to call for triggers, you simply do element.click(); and its clicked, which is so much cleaner.

and or for a completion sake as simple as:

location.search.match("part_number")?
oElement.click() : 0;

Ain't that twice as clean and far more simple?

But once again [just for the sake of curiosity ]Trigger click event if page loaded from a certain referring URL
how do you translate this question into what you are saying now without some powerful trans-mutational alchemy?
